Convert Line Feature to Area Feature

Hello,
Is there a way to convert a closed line feature, e.g. contour line, from a line feature to an area feature?
I want to calculate the stage vs. storage volume for a reservoir. I contoured a DEM and have a closed contour near my dam crest. From a previous thread, know that I can assign an elevation to an area and then have GM give me the volume difference as a function of elevation.
Also, as I have a number of closed line features (contour lines) is there a way to have GM report the area within the closed line feature?
Thanks.
Russ

Russ,
You can select the line(s) with the Digitizer Tool, then right-click and select the Advanced Feature Creation submenu command to create areas from the lines. It should automatically connect closed lines. You can then right-click with the areas selected and under the Measure submenu select to Display Feature Measures. That should show a dialog with all of the enclosed areas.
Thanks,
Mike
